rllhis invention relates to a loading-plant especially designed Jfor building-stones of any kind, such as lime stones or sand stones, bricks, clinkers and the like. The apparatus is designed to pull the material Jfrom the hardening boilers, or kilns on platformwagons onto a loading bridge and thence upon the conveying wagon.

According to the invention this is made possible by pulling the platform-Wagons, which are in the hardening-boilers, kilns or the like loaded with bricks or stones, by means of a pullrope upon a loading-bridge mounted in a ditch on rails, this loadingbridge being then pulled out by the same rope from the ditch and rolled to a stopping-device so that, by the same rope, the loadingmaterial can be pulled from the bridge onto the conveying-wagon which, standing in 'front oi' the engine-house in which the winch for the pull-rope is mounted, is held by means of oscillatable hook-shaped arms so that it cannot shift in the longitudinal or transverse direction with regard to the track. l

An embodiment of the invention is shown, by way of example, in the accompanying drawings, in

Fig. l in side elevation partly in section and in Fig. 2 in top plan view partly in section.

Figs. l;L and 2a are continuations of Fig. l and Fig. 2 respectively.

In front of the hardening boiler, brickkiln or the like for the stones or bricks to be loaded a ditch a is arranged in which a loading bridge c is standing on a track The bricks e or stones piled in the hardening boilers and the like upon platform-wagons d are pulled upon the loading-bridge c by means ot a pull-rope f through theintermediary of a capstan g.

On each loading wagons Z can stand.

The pull-rope f is operated from an engine (motor) h by means of a gear-wheel-mechanism c and rope-pulleys 7c accommodated in an engine-house Z at the end of the track Z). The track b does not extend close to the engine-house but leaves, in front of the same.

bridge two platformsuflicient free space for a conveying wagon m. A rack n at the end of the track forms a stop for the loading-bridge as it can securely hold a supporting arm o of said bridge.

Gn the bridge ca trap p` is arranged which 5| is balanced by a counter-Weight Q with pullrope-1.

On the engine-house Z arms s having hoo is the front end are oscillatably mounted which are controlled by pull ropes s andV counter-weights g.

rlhe operation is as follows:

After the platform-wagons Z loaded with stones or bricks have been pulled from the hardening boilers, kilns or the like upon the loading bridge c by means ot the pull-rope f with the aid ot the capstan g, the loadingbridge c pulled by means of this pull-rope from the ditch a on the track Z1 up tothe stop or rack a which stops the loading-bridge through the intermediary of the arm 0. 'Vhen trap pf has been lowered onto the conveying-Wagon m, which is blocked in its pesition by the lowered hook-shaped arm s against accidental'shifting in longitudinal or transverse direction, the stones or bricks can be pulled by means of the pull-rope f onto the conveying-wagon m.

e The advantage ofthis improved loadingplant in comparison with the commonly used leading plants or apparatus is, that only one singlewinch is sufficient 'for pulling the platform-wagons trein the kiln, for conveying the loading-bridge and for transferring the bricks or stones from the loading-bridge onto the-conveying-wagon. Up to they present two separate smallvengine-hofuses, each with its driving engine consisting of an electric common oil or benzin-motor, were required so that a rational an-d economical working is impossible. The double engine houses, double engines and accessories consume double power and demand the double attendance.

A serious inconvenience of the commonly used loading-system is that much time is lost during the transferring of the charge by troublesome lowering and elevating. By the high stress to which the engine and mechanism are submitted, the elements which eXelll() cute a sliding, rubbing or rotating action, are excessively worn the more as sand gets between the elements so that the plant becomes frequently unfit for use for a longer or shorter time.

In addition to the enormous cost for repair a considerable loss is caused by the impos sibility to use the plant. All these inconveniences are obviated by the new system, the working process being considerably shortcned, the cost of one engine-house and engine,

the power tol operate the latter as well as the wages of the engineer being saved. No slow elevating, lowering and pushing over of the material is necessary which operations con sume much energy.

Repairs are almost excluded and can scarcely happen in the plant according to the invention so that no interruption of work will occur. lThe initial expenses are less than half of the expenses for the commonly used loading-plants, the eii'iciency being much greater.

A loading-plant for stones hardened in hardening-boilers, comprising in combination platform-wagons for the material in the hardening-boilers7 a` ditch in front of the hardening-boiler, an engine-house at some distance from said harlening-boiler7 a track in said ditch and extending to a short distance from said engine-house, a loading bridge in said ditch on said track, a trap on the front end of said loading bridge, a conveying wagon between said engine-house and the track end, a capstan on said track, a winch in said engine-house7 an engine for driving said winch, a pull rope from said engine-house for pulling said platform-wagons with the material onto said loadingbridge, and for pulling said loading bridge over said track to said conveying wagon, and the material from said loading bridge over said trap onto said conveying wagon, an arm downwardly inclined and ixed on the axle of the front wheels of said loading-bridge1 a stop consisting of a rack at the end of said track designed to securely hold said inclined arm, and arms having hooks, oscillatably mounted on the outer wall of said enginehouse and designed to securely hold said conveying wagon so that it cannot shift in any direction with regard to said track.

In testimony whereof I ailix my signature.
